2D perovskite induced self-organization of conjugated chromophores for efficient and stable optoelectronic applications. (Research)

The burning of fossil fuels brings along considerable pollution of the environment and is, unfortunately, a major cause of global warming. As a consequence, it is desirable to move towards the widespread use of renewable energy as soon as possible, among which solar energy can take up a prominent role. A relatively new type of solar cells based on the hybrid organic-inorganic perovskites (HOIP) technology promises to combine high efficiencies with low costs. However, all demonstrated devices still suffer from a poor stability leading to a fast degradation of their performance. Therefore, the goal of my research project is to gain a deeper understanding of the behaviour of these materials and to develop a new class of 2D layered HOIPs including conjugated chromophores as organic layer in the search for novel multidimensional HOIPs with enhanced charge transport properties, increased absorption and improved ambient stability. To achieve this, a range of new materials will be prepared and analysed to discern trends related to structure-property and contribute to their fundamental understanding. The knowledge gained from this study will surely contribute to the use of these materials in emerging stable and efficient optoelectronic applications.
